Can I use this for complex CLI tools?

Yes, the skill includes templates for subcommand dispatching and self-documenting help text, making it ideal for building sophisticated command-line utilities.

How does the skill handle error reporting?

It implements a standard error-handling pattern using specialized shout, barf, and usage functions, providing consistent exit codes and stderr messaging for better debugging.

What makes this skill different from regular shell generation?

This skill strictly adheres to POSIX standards and UNIX philosophy, ensuring scripts are portable, modular, and follow rigorous engineering practices like atomic file writes rather than simple redirection.

Does this skill support Bash-specific features?

No, this skill is specifically designed for POSIX-compliant scripts (#!/bin/sh) and avoids Bashisms to ensure maximum portability across all UNIX-like systems.

关于

This skill enables Claude to author and maintain professional-grade POSIX shell scripts that prioritize portability, reliability, and modularity. By enforcing strict quoting rules, standard error handling patterns, and atomic file operations, it transforms shell scripting from a collection of ad-hoc commands into a disciplined engineering practice. It is ideal for developers building system utilities, automation scripts, and deployment tools that must run consistently across various UNIX-like environments without Bash-specific dependencies.
